A lot of moisture in insulated outbuilding

[mderoy]

I went to help a friend of mine wire up some network Ethernet ports to an outbuilding office he recently had built. It was built with a really good foundation from what I could see. Dug deep and insulation added and concrete poured in. The walls are those grey aerated blocks but sandwiched together with insulation in between. The roof is flat roof with insulation too. Exterior was rendered and painted. Windows and doors are double glazed and electric heating which heats to room quite well and heat retention is good doesn’t get cold quickly. Interior walls are dot and dabbed plasterboard. C

The problem is that he is having to run a dehumidifier constantly 24/7 regardless of usage and the container gets filled with water literally in about 6/7 hours. The window vents were closed so I told him to try keeping them open but it hasn’t helped.

Just wondering if anyone can shed any light on what could be wrong?

Thanks

Is this construction moisture, habitation moisture or recent weather conditions? He isn't running a gas heater in there is he?

No there is no gas heater in there. It’s just purely electric heating. How do i know what kind of moisture it is? I mean weather has been cold lately but the moisture issue seems to still be same regardless of outside temperature. Maybe it’s construction moisture? It can’t be habitation moisture because it’s not being used at the moment and it’s collecting a lot of water in the dehumidifier.

Likely still drying out if it has just been built.

Make sure the dehumidifier is suitable for the area involved, keep it on and close all vents. Wait until the amount of moisture being collected reduces
